I'm currently looking for a way to control a variable voltage (9V-18V) DC brush motor. The spec calls for the motor to be PWM controlled with at a frequency of 200Hz +/-10% With a duty cycle ranging from 50% to 100%
Since we'll be using an SLC 500 (probably 5/03) for other controls anyway; I was looking for a way to incorporate it.
I had hoped for a Plug and Play module. But I can't seem to locate such an animal. My second thought was to use an analog output module to send a variable voltage to control the duty cycle.
One problem is that we need to control 8 of these motors on one fixture. I'm hoping to avoid designing and building "one off" boards in this case, as that sort of thing often comes back to haunt us later.
Any ideas or suggestions are greatly appreciated!
